Problems solved by technology

[0003] Due to the complex and changeable offshore environment, offshore wind turbines are much more difficult than onshore wind turbines from pile foundation construction to complete machine installation. The length of a wind turbine tower is generally 70-80 meters. If the overall hoisting is installed on the pile foundation, hoisting During the process, the lifting level of the tower cannot be guaranteed, especially in the case of strong sea wind and floating waves, the tower is more likely to shake, which brings great difficulties to the lifting and installation of the tower; secondly, the installation of wind turbine blades at sea When it is connected to the hub of the nacelle, quick positioning and installation cannot be achieved, the blades are easy to get stuck, and need to be disassembled and reinstalled, which is time-consuming and labor-intensive

Abstract

The invention relates to an installation technology of an offshore wind turbine generator. The technology comprises the following steps that a platform moving ship is positioned and jacked up, a positioning barge drops an anchor in place, a transporting barge is in place, a tower drum is turned over, blades are turned down, a fan tower drum is hoisted, a cabin hub is hoisted, and the blades are hoisted and installed; and the step of sequentially hoisting the fan tower drum comprises bottom-section tower drum hoisting, middle-section tower drum hoisting and upper-section tower drum hoisting. The technology has the advantages that the tower drum is installed and fixed in a segmented mode, rapid positioning is achieved, the hoisting stability and levelness of the tower drum are guaranteed, and rapid and accurate positioning of the blades is achieved.

Description

Technical field: [0001] The invention relates to the field of wind power generation, in particular to an installation process for offshore wind turbines. Background technique: [0002] Offshore wind turbines (abbreviated as offshore wind turbines or offshore fans) are a new type of power generation equipment used for offshore wind power generation. Fixed on the pile foundation, the tower head is installed on the top of the tower tube, and the pile foundation is set on the seabed to support and fix the tower tube. The pile foundation plays a vital role in the safety of the offshore wind turbine. [0003] Due to the complex and changeable offshore environment, offshore wind turbines are much more difficult than onshore wind turbines from pile foundation construction to complete machine installation. The length of a wind turbine tower is generally 70-80 meters. If the overall hoisting is installed on the pile foundation, hoisting During the process, the lifting level of the to...
